Seventy percent of this 2 percent of fresh water is solid glaciers, located in the inaccessible mountains and the North and South Poles, and the price of water is getting higher and higher.

In fact, there were seawater desalination technologies in the world before, but the cost of these technologies was too high, and this technology would only be used in some extremely water-scarce areas, which was not popular in the world, and the desalination technology after 99 years was filtered through a biological network.

That kind of biological web is woven together with the silk of the mutated red spider and the silk of the special Masang silkworm, and after some special chemical treatment, it forms a special biological filter, after this kind of web is made, as long as the seawater flows through the biological filter, the salt in the seawater will be automatically blocked, and only fresh water will flow through.

The whole process is very simple, in addition to the production of biological filters requires a certain cost, other aspects do not need any investment at all, and the production of an area of 100 square meters of biological filters, the cost is only about 2,000 yuan, even if the selling price is 10,000 yuan, and just such a network, theoretically able to filter the volume of water, reached 100 million cubic meters, that is, 100 million tons of water.

If according to the current water price in most cities, the price of this million tons of water is 100 million, and now, you only need 10,000 yuan to buy a biological filter, and then there is enough seawater resources, the difference is 10,000 times! Therefore, the cost of this desalinated seawater can be said to be extremely low, extremely reasonable, and easy to spread around the world.

After mastering these four techniques completely, Yan Feng's eyes also showed a smile, if Aunt Li knew these techniques, she would definitely be very happy, right?

However, with the scientific and technological strength of Xinlong Group, I am afraid that it will be difficult to provide myself with a biological laboratory of sufficient grade, and I am afraid that I will have to find someone to help, but I will talk about these later. After all, the manpower of Xinlong Group is limited, and it is currently stepping up the launch of Xinlong induction cooker, and Xinlong refrigerator has not yet been launched. "Continue the draw!"

As soon as the voice fell, four options appeared in front of Yan Feng again. And Yan Feng also patrolled with a billiard cue, I don't know if I don't smoke, I was scared and shocked, but I didn't expect that just one lottery would consume his five hundred merit points.

Now, half of his 1,000 merit points have been consumed. It seems that it needs to be saved, a future technology lottery has been conducted, Yan Feng naturally cannot do it again, life skills are too small compared to survival skills, although Yan Feng now lacks a tailor skill, but the probability of drawing is too small.

By the way, it seems that my sister also wants a pet. In addition, Yuzi is also his girlfriend, he can't favor one over the other, it seems that he needs to draw two pets again, and then, Yan Feng directly picked up the club, and then hit it out.

The black ball shot out and hit the white ball near the Super Pet lottery option, and then the white ball went into the hole. Then, the ball case became half the original size, and the lottery options on it also changed: "Wind Leopard", "Lightning Marten", "Lightspeed Cat", "Thousand Faces Phantom Demon".

When Yan Feng saw these four pet names, there was a hint of satisfaction in his eyes, whether it was a mink or a cat, they were all cute pets that were easy to attract girls. It's really good, and the wind leopard should be good, but it's too big to go out with it. So Yan Feng gave up the wind leopard.

As for the thousand-faced phantom demon, it should be a pet that can create illusions, and I don't know what it looks like, but it should be good, normally if Yan Feng doesn't want to waste merit points, four options, two are the most suitable, and three is a bit risky, and this time, Yan Feng is also going to draw three pets.

Of course, the lightning marten and the lightspeed cat are the mainstays, as for the thousand-faced phantom demon, you can draw the best, and when the time comes, you can't draw it, Yan Feng is not disappointed, and then, Yan Feng picked up the club in his hand and began to hit the ball, the first shot, the target is the lightning marten.

In the Eight Divisions of the Heavenly Dragon, there is also a lightning marten, which is white, extremely beautiful, fast as lightning, and has a violent poison itself, feeding on poisonous snakes, but this lightning marten was poisoned to death by the reckless Zhu clam, known as the king of ten thousand poisons, I don't know what this reckless Zhu clam I extracted will look like?

Immediately, the black ball was hit out by Yan Feng with a club, and then hit a white ball, and the white ball was directly knocked into the hole where the lightning mink was, and the white dragon's voice also sounded: "Get the super pet lightning mink, do you want to receive it?"

Yan Feng listened and said, "Wait a while!"

Yan Feng said, looked at the situation on the ball case, and sighed secretly in his heart, it seems that this thousand-faced phantom demon cannot be extracted, if it is extracted, it will need to waste a hundred merit points, and this thousand-faced phantom demon does not have to be extracted, so he can only give up.

Then, the second ball was hit, and another white ball was hit into the hole where the lightspeed cat was, and then, the white dragon said again: "Draw the super pet lightspeed cat, do you want to receive it?"

Yan Feng listened and said directly; "Get it all!"

As soon as the words fell, two pets, one white and one amber, fell on Yan Feng's shoulders in mid-air, the lightning marten was the pure white one, with snow-white hair all over its body, its body was petite and beautiful, and its eyes were red, extremely beautiful, and the lightning marten liked to lie on the owner's neck very much, it looked like a fluffy scarf.

The appearance of the lightning marten makes Yan Feng very satisfied, and the light-speed cat is not bad, the light-speed cat looks like a big gap with ordinary creatures, the whole body seems to be transparent, the color is amber, and the body seems to release a trace of light, the form, it is very similar to ordinary domestic cats, but the body is more petite and exquisite.

If the lightning cat squatted there and did not move, it was very likely that people would think that it was a jade product, of course, it was a work carved by a master figure with the highest level of topaz who carved out a creature with very high technology, and it was definitely priceless, thinking about it, Yan Feng said, "Can you show your ability?"
